Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624

; Check handling of the mftb instruction.
|
|
; For CPUs 601 and pwr3, the mftb instruction should be emitted.
|
|
; On all other CPUs (including generic, ppc, ppc64), the mfspr instruction
|
|
; should be used instead. There should no longer be a deprecated warning
|
|
; message emittedfor this instruction for any CPU.
